WALTER FAAS, OF SAN DIEGO, CALIFORNIA.

PHOTOGRAPHIC ACCESSORY.

Application led April 22,

To ali whom t may concern:

Be it known that I, "WALTER Faas, a citi- Zen of the United States, resident of San Diego, in the county of San Diego and State of California, havev invented certain new and useful Photographic Accessories, of which the following is a specification.

This invention relates to photographic accessories, having more particular reference to a means for quickly determining the most suitable size and outline to be given the prints from any negative, being intended more particularly for the use of professional photographers although not in any way limited to use by the same.

The invention has for an object to provide a simple means by the use of which selection of the mask to be used on the negative to give the most suitable size and outline of picture is greatly facilitated, enabling such selection to be made with a minimum of handling thereof and of the masks, and resulting in considerable saving of time.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings in which the invention is set-forth in detail,

the various combinations, sub-combinations and featuresA of construction forming the invention being set forth more particularly in the appended claims.

In carrying out my invention I provide, briefly speaking, avselecting, or test device which I term a test mask, or trial mask which is adapted to be placed in suitable positioning vwith, respect to the negative from which the print is to be made, being preferably placed on the negative. In conjunction with this trialV mask I provide a series of true masks presenting different or differently arranged apertures, the trial mask being arranged so that the part of the negative which would be revealed through any one of the true masks can be seenat a glance while suitable indicating characters are provided for determining which of the true masks has the corresponding exposure aperture.

In the accompanyingdrawings I have illustrated the invention as embodied for use in connection with the most commonly employed picture outlines, it being understood that the arrangement may be varied to suit any outline that may be established by c ustom, or that may be desired.

Specification of Letters Patent. Patufed Jan. 17, 1922 1921. Serial No. 463,527.

Figure l of the drawings is a face view of a trial mask as arranged for use when pictures of circular outline are to be producedL Figures 2 to 7 inclusive are face views of the different true masks which may be selec'ted by the use of the trial mask. n

Figure 8 is a face view ef a trial mask as arranged for use when pictures of oval outline are to be produced.

Figure 9 tor la inclusive are face views of the diderenttrue masks which may be selected 'by the use of the trial mask shown in Figure' 8.

'Figure l5 is a face view of a trial mask as arranged for use when pictures of rectangular out line are to be produced.

Figures 16 to 21 inclusive are face views of the different true masks which may be selected by the use of the trial mask shown in Figure 15.

The diiferent trial masks are indicated by the reference numerals i, l and la which designate respectively the forms shown in Figures 1, 8 and l5. These trial masks may be of such outline as is desired, generally rectangular, and are preferably made of transparent paper of stiii parchment like quality. They might also be made of glass, in which case the enclosure thereof in a suitable Vframe would be desirable to prevent breakage during handling.

Y The various series of true masks are indicated generally by the reference numerals 2, 2 and 2zL which designate respectively the forms shown in Figures 2 to 7, 9 to 14, and 16 to 2l, these masks having exposure or printing apertures 3, 3 and 3a respectively, therein, the apertures of the different masks ofV eac'hfseries being of suitable progressively varying sizes. These true masks may be the ordinary type of mask which is made of black paper.

Upon each of these trial masks are printed, painted, or otherwise placed, a series of lines indicated generally at 4, 4 .and 4 for the respective trial masks, these lines being arranged in correspondence to the different series of exposure apertures 3, 3 and 3a, the lines on the trialV mask l being of circular outline; of the trial mask l', of oval outline; and of the trial mask la, of rectangular outline.

The different lines of the respective trial .these lines in .F and the spaces enclosed by the diierent lines correspond to the exposure apertures 3, 3 and 3a, of the series Vot true masks.

The series or' linesron the trial masks areV suitably numbered, as here shown from one vto six, 'While each series of true masks is correspondingly numbered, it being understood 01"' course that the true'mask has the same number as the line which enoloses a space equal to that or the exposure aperture in the true mask. `The lines and numbers `on p the trial'masks should be fairlylieavy, so as to ybe readilv visible when viewed as a rilied to the negative,.ivhi le the numbers on the true masks Will naturally` be iii a light color toghe I readily seen.

YVthe light-and since the relation etalt is believed that the manner of use of Y my invention Will be YreadilyA understood from theV above description Thetrial-inask is placed on the' negative and viewed against Y the lines on the mask to the picture on the negative is seen atonce, the most suitablesize for the printed picture can be .seen .at a glance and the correspoi'iding true mask iinmediatelyselect'ed, and a considerable saving or' time effected since the individuel applica- 'tion ofthe diiierent true masks .to theY nega` tive until the most suitable one is found isv rendered unnecessary. e

llhile l have indicated an arrangement in Which there are only` six masks in'each series, it is to be understood that this number may be varied as mayjseem desirable, and that other changes ormodifications, not herein Y set forth or referred to,}may be made in care loivs rying out the linvention Without departing from vthe spirit and scope thereof.

Having thus 'described my invention, whatv claim as newanddesireto protect by Let-V ters Patent ot' the United States isas-oll.
